Why does the shape differ when importing an SVG file?
To increase the resolution of the Curve Object see this panel. There's a setting for Preview and Render resolution.



The SVG itself is also stretched in the width, internally it's showing a non-proportional viewbox property. Each coordinate is transformed according to the viewbox ratio.

viewBox="0 0 1 1.41379"




save it again from CorelDraw with proportional dimensions (can't help you with that) or edit the .svg manually (easy). Look for the line with viewBox="0 0 1 1.41379" and change it to viewBox="0 0 1.41379 1.41379", or "0 0 1 1"
